SMB1001 is a cyber security certification for small and medium businesses, and email authentication sits inside its controls for protecting your domain and your customers. In practice that means publishing SPF and DKIM for every service that sends as you, and a DMARC (RFC 9989) policy that tells receivers what to do with mail that fails, with reports flowing back so you can prove it works.
Which controls apply depends on the certification level you are aiming for, so the first step is matching each requirement to evidence you already have. The EmailAuth AI Agent reads your domain's live DNS, shows which records are in place and which are missing, and helps you build a clear evidence trail for your assessor.
